Water-cooling motor case and motor

Abstract

The invention discloses a water-cooling motor case, and the motor case comprises a case body, wherein the case body is provided with a cooling water inlet, a cooling water outlet and a heat exchange water channel connected with the cooling water inlet and the cooling water outlet. The cooling water inlet is arranged on one end of the case body, and the cooling water outlet is disposed on the otherend of the case body. The heat exchange water channel includes a first water channel and a second water channel, and the cooling water inlet is connected with a water inlet of the first water channeland a water inlet of the second water channel. The cooling water outlet is connected with a water outlet of the first water channel and a water outlet of the second water channel. The first water channel and the second water channel are bent along the outer side wall of the case body, and the first water channel and the second water channel are symmetric relative to center of the case and distributed on the outer side wall of the case body. According to the invention, the cooling water channel of the motor case can be effectively optimized, thereby effectively improving the heat dissipation efficiency, and improving the overall performance of a motor. The invention also provides a motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a water-cooled motor casing and a motor. Background technique [0002] At present, since the motor will generate a certain amount of heat during energy conversion, it is necessary to dissipate the heat generated by the motor in a timely manner during the operation of the motor, otherwise the motor temperature will be too high, which will lead to a decline in the performance of the motor, and even damage the inside of the motor circuit. [0003] In the prior art, the motor is the main component of a pure electric vehicle. With the continuous improvement of the power density of the motor, the heat dissipation capability of the motor is also continuously improved. Generally, the water channel sealing cooling method is used to cool the motor. However, the existing water channel sealing The method mainly adopts a single water channel structure, and the heat generated by the stator win...
